Abstract: A vehicle shock absorber has a body extending between a first end and a second end. Translation of a primary shaft within an interior cavity of the body communicates a first volume of fluid within the interior cavity to a secondary reservoir where it increases pressure in a gas cavity therein. The primary shaft has an annular member engaged thereon which contacts a bump shaft slidably located in an opening at the first end of the body. The contact of the annular member translates the bump shaft within the interior cavity to cause communication of a secondary volume of the fluid to the secondary reservoir.
